Punjab Police sources said that even otherwise the security of Davis had been tightened in view of serious security concerns that include some subversive act from India to get the double-murderer to embarrass Pakistan.

“In sheer frustration, the Americans are capable of conducting a sting operation for which we are ensuring that all security measures are taken on our part,” a Punjab administration source said, adding that the security of Davis was being shaped up while keeping in mind all possibilities whether regarding an assault on him, a terrorist attack and even a strike by US commandos to get him forcibly released.

A Punjab government spokesman and secretary information, Mohyuddin Wani, when approached, confirmed that Davis would be taken to the Kot Lakhpat Jail where he would be placed in a special cell which is detached from the normal barracks but set up for high-profile and high-value prisoners.

“It is highly protected and fully secured,” Wani said, explaining that all possible security measures would be taken, including multiple security cordons for the protection of the double murderer. Wani said that Rangers would also be deployed in the outer cordon.

“We would ensure by using all means to protect and secure the prisoner,” he said. The secretary information, however, offered no comment when asked if the possibility of a sting operation by the US forces was also discussed. The Punjab government spokesman said that Davis would not be held in isolation in the jail but would be kept with some foreign prisoners. Davis, who would be produced before a Lahore magistrate on Friday, is expected to be sent on judicial remand.

According to sources, the Punjab government was under pressure to notify some rest house or hotel as jail for the comfort of Raymond Davis but the authorities decided that like any other criminal, Davis should be sent to jail. However, the source said, it is ensured that the American killer is not exposed to the kind of inmates who may try to harm him.

During his remand with the police, Raymond Davis did not cooperate with the police, except what he had uttered during the initials few says of his arrest. Though he claimed to have killed two young Pakistani in self-defence, the police investigations have proved his plea of self-defence wrong. According to the sources, one of the two young men was killed from a distance of 51 feet and in a situation when the deceased was running away from the killer.

Police investigators see his act as an excessive and disproportionate use of force, which is not covered in the definition of self-defence as per the law of the land. Without having been fired at or threatened to death, the police sources said, Davis killed the two young men by excessive and disproportionate use of force.

Because of his non-cooperation, the police though could not probe Davis about his covert and overt activities. The provincial government has constituted a joint investigation team comprising police and members of intelligence agencies to analyse the material and gadgets recovered from the American killer.
